Application filed June 1, 1917. Serial No. 172,280.

To all whom it may concern:

Be it known that I, BERT V. WHITE, a citizen of the United States, residing at Condo, in the county of Spink and State of South Dakota, have inventednew and useful Improvements in Feeders for Corn-Shredders, of which the following is a specification.

This invention relates to feeders for corn shredders and it has for its object to produce an improved device of this class which will be simple in construction and eflicient in operation.

A further object of the invention is to produce a feeder of the class described which includes coacting lower and upper conveyers, the upper conveyers being resiliently supported to adapt themselves to the mass of material that is being fed, and shields being provided to guide the material beneath the upper conveyers.

A further object of the invention is to produce a feeding device of the class described having spring pressed doors to guide the material as it issues from the feeder, to prevent twisting movement thereof and to insure its being fed in the best and most efficient manner.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form .of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings:

Figure 1 is a top plan view of the improved feeder.

Fig. 2 is a side elevation of the same.

Fig. 3 is a longitudinal sectional view.

Fig. 4: is a bottom plan view.

Fig. 5 is a transverse sectional view.

Corresponding parts in the several figures of the drawings are denoted by like characters of reference.

The frame of the improved device includes side members 15 which are connected and spaced apart at suitable intervals by cross bars 16 supporting a floor member or ness oftheplatform and which should be.

so arranged that the upper portions of said rollers will lie substantially in the plane of the top face of the platform. Supported on the platform, about midway between the side members 15, there has been shown a longitudinal dividing member 21. Endless conveyer-s are guided over the rollers 19,.

20, each of said conveyors being composed of chains or belts 22 and slats or raddles 23.

Supported on the side members and on the longitudinal dividing member near the rearward ends of said members areupwardly extending brackets 24: having laterally extending arms 25. Conveyer frames C are supported intermediate the side memhers and the longitudinal dividing member, each of said conveyer frames comprising side members 26 that are suitably connected and spaced apart by'platform 27, said side members affording bearings for front and rear rollers 28, 29 over which endless conveyers composed of chains or belts 30 and slats or raddles 31 are guided. The side members of the conveyer frames C have bolts 32 extending vertically therethrough and upwardly through the arms 25 of the brackets 24. which are apertured for the passage of said bolts, the latter being provided with nuts 33 whereby the downward movement of the conveyer frames are limited. It will be observed that the conveyer frames C are supported above the platform 18 of the main frame and also above the top leads of the conveyers guided over the rollers mounted in said main frame.

Shields 34 of arcuate form are supported on the side members and on the longitudinal dividing member of the main frame adjacent to the rearward ends of the conveyer frames C, said shields being of arcuate form and so proportioned as to deflect any material passing over the platform of the main frame and exhibiting a tendency to rise above the conveyer frames C in a downward direction beneath said conveyer frames. The side members of the frame also support brackets 35 afi'ording bearings for a shaft 36 carrying band cutters 37 of any approved form and adapted to be driven in any con venient manner.

' der, however,

The shaft 38 of the rear roller 20 is adapted to be driven by power derived from the shredding machine in connection with which the improved feeder is to be used and it has for this purpose been shown as being equipped with a band wheel 39; the shredhas not been shown, being no part of the present invention. The roller shaft 38 is provided with pinions 40 meshing with pinions l1 that are supported idly on stub shafts 42. Said pinions 41 have sprocket wheels l3 associated therewith, and the shafts 44: of the rear rollers 29 of the conveyer frames 0 are provided with corresponding sprockets 45 receiving motion from he sprocket wheels 4:1 by transmission chains 46. Spring actuated chain tighteners .7 are provided for the purpose of maintaining the chains 46 under proper tension as the conveyer frames rise and fall during the operation of the device, as may be occasioned by the varying quantities of material that are being fed.

The side members of the main frame are extended rearwardly of the rear roller 20 to support a feed board as above the said feed board the side members are beveled as shown to produce what may be termed. triangular brackets 49 adjacent to the upper ends of which is supported a shaft 50 on which feed doors 51 are hingedly mounted, said doors being adapted to rest, when closed, on the inclined front walls of the triangular brackets. Springs are provided, said springs engaging the feed doors and tending to keep them normally in a closed position. Springs 53 may also be coiled on the bolts 32 to resist the upward movement of the floating conveyer frames G.

In the construction of a machine in accordance with this invention, the longitudinal dividing member 21 may be dispensed with in which event a single conveyer will be guided over the rollers of the main frame and a single floating conveyer frame will be used. 911 the other hand, additional dividing boards may be provided, in which event it is obvious that additional conveyers will be used.

In the operation. of this invention, the corn that is to be fed is placed on the platform 18 and is carried by the conveyer or conveyers guided or er said platform beneath we ness the floating conveyer frames C, being thus acted upon by the conveyers guided over said frames. The material will thus be held in compact form while it is being moved rearwardly until it passes beneath the feed doors 51, the latter being forced open against the resistance of the springs 52. The material as it issues from the feeder will thus be held very compactly and will have no tendency to twist or to turn as it is being fed to the snapping rolls of the shredder, thereby avoiding the stoppages and the im perfect work which is frequently due to the corn stalks being presented sidewise instead of lengthwise to the snapping rolls. The improved feeder is simple and it has been found to be thoroughly elficient for the purposes for which it is provided.

Having thus described the invention, whatis claimed as new is:

1. In a machine of the class described, a main frame comprising side members and a platform, rollers supported in the side members adjacent to the front and rear ends of the platfornnan endless conveyer guided over said rollers and over the platform, a floating frame supported above the endless conveyer and adjacent to the discharge end thereof, an endless conveyer carried by said frame, means for driving the endless conveyers, a feed board supported beyond the discharge end of the first mentioned conveyer, and hingedly supported doors closing in the direction of the feed board.

2. In a machine of the class described, a main frame comprising side members and a platform, rollers supported in the side members adjacent to the front and rear ends of the platform, an endless conveyer guided over said rollers and over the platform, a floating frame supported above the endless conveyer and adjacent to the discharge end thereof, an endless conveyer carried by said frame, means for driving the endless conveyors, a feed board supported beyond the discharge end of the first mentioned conveyer, hingedly supported doors closing in the direction of the feed board, and actuating springs to resist the opening movement of said feed door.

In testimony whereof I have affixed my signature.
